SFECIFICATION forming part of Letters Patent No. 294,444, dated March 4,1884.

Application filed December 28, 1883. (No model.)

To aZZ whom itmay c0ncern.--

which the upright portions of the stiffeners are made to assume thedesired shape by applying pressure successively to all parts there- .ofbymeans of rolling contact-surfaces, and it consists in certain novelconstructions, arrangements, and combinations of parts,which will bebest understood by reference to the description of the drawings, and tothe claims to be hereinafter given.

Figure 1 of the drawings is a plan of my improved machine for shapingheel-stiffeners. Fig. 2 is a vertical longitudinal sectional elevationof the same, the cutting planebeing on line 10 w on Fig. 1. Fig. 3 isatransverse sectional elevation, the cutting plane being on Fig. 4 is ahorizontal section through the former and pressure-rolls on line 3 y onFig. 2. Fig. 5 is ahorizontal sectionthrough the former andpressure-rolls on line 2 a on Fig. 2. Fig. 6 represents a partialvertical section of the former and the pressurerolls on lines o o o, thepressure-rolls having been revolved by the inward movement of the formertill the points 1; on the rolls and former coincide; and Fig. 7 I is asimilar section in the planes '0 0 0 Fig. 4, when the pressurerolls havebeen revolved by the inward or rearward movement of the former to suchan extent that the points '0 on the peripheries of the rolls and thepoints 1: on the sides of the former coincide with each other. 7

A is the table or bed of the machine, supported by the legs A A, andhaving formed in its front end the slot A, in which is fitted so 'as tobe reciprocated therein the crosshead B, upon the upper side of whichare secured or cast the former-O .and the two series of rack-teeth aa,as shown in Figs.1,2,and 5.

D and D 'are two heavy steel springs secured to opposite sides of thestand D cast upon or secured to the upper side of the table A, as shownin Figs. 1 and 2. These springs D and D carry at their front ends thevertical journal-pins b and b, respectively, upon which pins are mountedso as to be free to revolve thereon the rolls E and E, as shown in Figs.1, 8, and 4. The rolls E and E are not necessarily circular incross-section, and in fact I prefer to form upon each of them one fiatside a, as clearly shown in Fig. 4, by means of which said rolls aremaintained injthei'r normal positions shown in said Fig.4 until they aremoved therefrom by the rearward movement of the former O and therack-teeth a and a,

which teeth engage with the spurfgear wheels F and F,secured to orformed upon the lower ends of the rolls E and E, respectively. Thegear-wheels F and F are so formed that when the former O is moved towardthe front of the machine, after having shaped a stiffener, the rollswillbe revolved in the directions indicated by the arrows until the fiatsurfaces 0 thereof are contiguous to each other, when the rack-teeth aand a will be disengaged from the teeth of the wheels F and F, and thecrosshead B, carrying with it the-former C, may be moved still farthertoward the front end of the machine without affecting the positions ofthe rolls,they remaining in the positions shown in Fig. 4until, in therearward movement of the cross-head and former, the rack-teeth engageagain" with the teeth of the gear-wheels, as shown in Fig. 5.

In order to produce a properly-shaped heelstiffener, it is necessarythat the former should have its sides curved both longitudinally andvertically, and that the vertical curve of its sides should vary atdifferent points in its length, and that any rolling-surface working inconjunction therewith shall. be so shaped as to conform to and beparallel with the varying curved surface of the former, as is shown inFigs. 2, 6, and 7. The cross-head B has pivoted to its under side oneend of the link G, the op posite end of which is in turn pivoted to themovable end of the lever H, mounted upon and firmly secured to therocker-shaft I, which has its bearing in boxes J J, cast upon. orsecured to the table A, and has secured to one end thereof thehand-lever K, by which a reciprocating motion may be imparted to thecross-head B and former O. This arrangement of lovers, &e., may be usedwhen the machine is to be operated by hand; but to make a power-machinea crank-shaft and pulley may be substituted for the levers H and K andthe shaft I. The tension of the springs D and D may be adjusted andregulated by the setscrews (1 d, which work in threaded holes in theears (1 d on the stand D as shown in Fig. 1.

From the upper side of the table A rise the two uprights, L L, one uponeach side of the rolls E and E, which have secured to their upper endsor formed therewith the flange-turning plate M, the front edge of whichhas formed therein the U-shaped notch e, the lower corner of which iscut away to a rounded bevel, as shown in Fig. 2.

N is a pawl, pivoted at f to cars projecting from the rear edge of theplate M in such a manner that it may be raised upward, but cannot fallbelow its normal position, in which position it is maintained by thecombined action of the spring tending to force it downward, and a flatsurface at its pivotal end, which engages with the edge of the plate M,and serves to limit said downward movement, all as shown in Fig. 2.

This machine may be used for shaping heelstiffeners from flat blanks,but is more especially designed and adapted to reshaping and turning theflange or heel-seat upon partiallyshaped stiffeners; and its operationis as follows The several parts being in the positions shown in thedrawings, the operator first moves the upper end of the hand-lever Kto-' ward the front end of the machine till the former 0 is sufficientlyremoved from the rolls E and E to permit the placing of a blank or apartially-formed stiffener between the former and said rolls, whichblank is then placed in position by the operator, with its straight edgeupward and the center of its length coinciding with the center of therear end of the former, care being taken that the blank orpartiallyformed stiffener shall project above the upper surface of theformer C a distance equal to the desired width of the flange orheel-seat to be formed upon the stiffener. The operator now moves thehand-lever to the rear, thus causing the cross-head B, the former O, andracks a a to be moved to the rear and press the blank or stiffenerbetween said former and the rolls E and E, in the positions shown inFig. 4, and the racks a and a to engage with the gearwheels F and F, asshown in Fig. 5. A eontinuation of the rearward movement of thecross-head B, the former O, and the racks a and a will cause the rolls Eand E to be revolved about their axes and said axes to separate fromeach other, so that the former C may pass between said rolls, carryingwith it the blank or partially-shaped stiffener, the tension of thesprings D and D causing the rolls E and E to wrap the blank around thesides of the former G, and, by virtue of the conforming shapes of thesurfaces of said rolls, press every part of said blank orpartially-formed stiffener that is below'the upper surface of the formerhard against the sides of said former and compel it to conform thereto.\Vhen the blank or partially-formed counter-stiffener is firmly heldbetween the former and the rolls E and E, the continuation of therearward motion of the former will cause that portion of the blank orpartially-formed stiffener which projects above the upper surface of theformer to be turned down upon and pressed hard to the uppersurlace ofsaid former by the action thereon of the U-shaped forward edge of theflange-turning plate M. The rearward move ment of the former G iscontinued until the blank or stiffener has passed from between the rollsE and E and the center of the flange or heel-seat thereof has passed tothe rear of the pawl N, which, after said flange or heelseat has passedit, drops upon the upper surface of the former, directly in front ofsaid flange or heel-seat, so that when the former is again moved towardthe front of the machine the rear or movable end of the pawl Nintercepts the forward motion of the stiffener by engaging with itsflange or heel-seat, and prevents further forward movement thereof,whilethe former is withdrawn therefrom into the proper position for theinsertion of another blank or partially-formed stiffener, the shapedstiffener, when the former is withdrawn therefrom, dropping through thehole 0 in the table A into any suitable receptacle provided for thepurpose, or upon the floor.

The rolls E and E, instead of being mounted upon the movable ends of thelong leafsprings D and D, as shown in the drawings, may be mounted uponcarriages or crossheads arranged to be moved toward and from each otherin slides arranged for the purpose transversely of the table A, saidcarriages or cross-heads being pressed toward each other by any suitablesprings or weights without affecting the principles of my invention.

It is obvious that the mechanism for revolving the rolls E and E may beso arranged that said rolls shall be revolved at a speed which willcause their exterior surfaces to move slower than the surface of theformer, and thus cause a rubbing action upon the stifi'ener-blank fromits center toward its two ends, if desired, or so that the meancircumferences of said rolls shall move in unison with the surface ofsaid former, thus reducing the rubbing action to a minimum and shapingthe stiffener almost wholly by rolling pressure, without affecting theprinciples of my invention.

What I claim as new, and desire to secure by Letters Patent of theUnited States, is-

1. In a machine for shaping heel-stiffeners for boots and shoes, thecombination of a heelshaped former having its sides and rear end moldedor shaped to present different contours or outlines when outtransversely at different points, and a pair of yielding pressure-rollsarranged to revolve about their axes toward each other, and to move inthe same direction as said former, and'havin'g their exterior surfacesmolded or shaped to conform to the va-' rying curvature of the surfacesof said former, substantially as and for the purposes described.

2. The combination of the former O, therolls E and E, and the springs Dand D, all

E, the gear-wheels F and F, the racks a and a, and the flange-turningplate M, all constructcd, arranged. and adapted to operatesubstantiallyas and for the purposes described.

5. The combination of the reciprocating former Ovand racks a'and a,,theyielding pressure-rolls E and E, the gear-wheels E and- F, theflange-turning plate M, and the stiff-.

ener-discharging pawl N, all arranged and adapted to operatesubstantially as and for the purposes described.
